Closed loop greywater treatment plants

​Closed loop greywater treatment plants processes recycles and reuses generated greywater while maintaining the same cleaning performance as current systems.

Generally, membrane ultrafiltration is used to reuse fresh water. For a clothes washer, the greywater reuse system consists of a closed-loop water recycle which can be redirected to a storage tank for other applications, or directly used in situ with a clothes washer for subsequent rinse cycles.
A greywater closed loop treatment system must hold a chief executive approval or its predecessor before it can be installed.
